Zusammenfassung:PROBLEM TO BE SOLVED: To provide a communication device capable of reducing user's labor concerned with authentication while considering security in a system allowing a plurality of communication paths to be used. SOLUTION: A mobile phone 11 performs authentication processing by a Bluetooth communication being a high-security communication path to a HDD recorder 10 and generates a link key by the authentication processing. In following communications between the mobile phone 11 and the HDD recorder 10, an encryption key is generated on the basis of the link key generated by the authentication processing, and communications are performed via the Bluetooth communication and the Internet 12.
